Explain how one can rate the closeness of related organisms by comparing dna base sequences

Biology
1 answer:
Harman [31]3 years ago
6 0
Scientists believe we all originated from one common ancestor. using our dna base sequences, we can determine how closely related organisms by looking at when the first differing sequence occurs. for example, U U T A you can determine that
U U T T 1 and 2 are more
U U A T closely related than 1 and 3 because their dna sequence stays the same for longer. hope this helps :)

How does the cell regulate the substrate specificity of ribonucleotide reductase to maintain equal amounts of all four deoxynucl
Kruka [31]

Answer:

The correct answer is A When dTTP is bound to the specificity site, more dCDP is produced

Explanation:

Ribonucleotide reductase catalyzes the conversion of ribonucleotide to deoxyribonucleotide.

                  When dTTP is bound to the specificity site at that time dCDP is produced.The So formed dCDP is converted to dUDP by the help of dCDP deaminase.The dUDP is then converted to dUTP by phosphorylation.

               Finally the dUTP is converted to dTTP by the catalytic activity of thymidylate synthase with the presence of N5 N10 methylene tetrahydrofolate.

        Thus equal amount of deoxyribonucleoside triphosphates  are maitained by the cell.

Flowers tend to respond to stimuli
Stimuli are anything that causes arousal or enables an object to respond or react.

There are many different kinds of stimuli for which is different for every organism, for example, water, light and carbon dioxide are three stimuli and materials needed for photosynthesis in plants to manifest.
<span>In humans, we have nutrients or food, oxygen and water for us to survive. These are stimuli, eyes need light as a stimuli for it see and function. Nasal receptors needs smell as stimuli caused by molecular reactions of an object as a stimuli. And others.<span>
